Application filed October 10,1912. Serial No. raises.

To all whom it may concern:

Be it known that I, GEORGE 1. SMITH, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a new and useful Lock for Automobile Clutch-Levers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it.

provision of two or more bolts and a pivoted member or tumbler co-acting together and adapted to be actuated by any form 0 Yale barrel or other mechanism, for looking or releasing the clutch lever. When looking the clutch lever one of the aforesaid bolts is actuated by a foot rod, so that a lug on the clutch lever may be engaged by the aforesaid bolts.

In the drawings there are disclosed certain features of construction, but in prac-; tical fields these features may necessitatei alterations, to which'the patentee is entitled,

provided the alterations are comprehended:

= tendsthrough an opening 9 of the dashwithin the scope of what is claimed.

Further features andcombination of parts are hereinafter set forth, shown in the drawings and claimed.

In the draw1ngs:F1gure 1 1s a view 1n elevation. of a'portion of a dash board of an automobile,show1ng the locking mechanism Fig. 2 1s a sectional as applied thereto. I view on line 2-2 of Fig. 1, showing the'two or more co -acting bolts and tumbler, partly in dotted lines, and in elevation, for locking the clutch lever against being actuated. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is a view similar to Fig. 3, showing the bolts and the tumbler in readmess to be actuated. .Fig. 5 is a view similar to Fig. 2, showing the clutch lever unlocked, and the co-acting'bolt's and tumbler in read;- ness to be actuated. Fig. 6 is a sectional view-on line 6-6 of Fig. 5. Fig. 7 is a sectional view on line 7-7 of Fig. 5. Fig. 8 islever.

a detail perspective view of the bolt, whichengages a lug of the clutch lever for locking the same. Fig. 9 is a detail perspective view of a portion of thev bolt shown m Fig.

8,'and showing thesame in engagement with the lug oft-he clutch lever- Fig. 10 is a-tletail perspective view of a portion ofanother form of bolt as shown in Figs. 8 and 9,1t0 engage a difi'erent form of lug on the clutch Fig. 11 is a detail view in perspective, showing the tumbler to be oscillated by an arm of a rocking member, which in turn or other locking mechanism.

Referring more particularly to the drawings 1 designates a portion of a dash board of an automobile, to which a-casing inthe form of a casting or the like 2 is secured by the screws or other means 3 and 4. The

upper portion ofthe casingis in the form ot a rectangular boxing or the 'like 5, through which the screws 3 pass and into the dash board 1,while the lower portion of the casing is cylindrical and provided with board, and has slida 1y mounted therein a bolt 10, at one end of which downwardly extending lugs or ears 11 are formed, one upon each side of the bolt. A conventional .form of automobile clutch lever is disclosed in the drawing, and to which clutch lever 12 a lug 13 is integrally or detachably connected, as shown at 14 in Fig. 2, and at 15 in Figs. 5 and 9. It is immaterial, however, how the lug 13 is connected to the clutch lever. This lug 13, when the clutch lever is depressed, as shown in Fig. 2, is designedto engage under the bolt 10, and between the lugs or earsll, that is, when the bolt '10 is partially withdrawn from the casing 8,

as shown in Fig. 2. In Fig. 10, the lugs or cars 11 are dispensed with, and the'boltlO is designed to engage a notch or. recess,16 of a diiterent form of lug 17 carried byxthe clutch lever 12;

is actuated by any form of Yale barrel anchored in place at one end. The other The bolt 10 has a pin 18 extending transversely thereof, to the reduced end 19 of which ajbowed spring 20 is connected, as shown clearly in Figs. 2, 5, 6, 7 and S. The

reduced end 19. of the pin with the connect-' ed end of the spring 20 moves partially in a cutaway portion or recess 21 :of the casing 8, while the endv 22 of the spring is seated in a notch 23 ofthee'ecess or cutaway portion, so as to hold the spring end of'the pin 18 terminates in a. reduced portion 24, which moves in a slot 25- of the casing 8. The slot 25 is formed in the casing opposite the recess or cutaway portion 21.

To move the bolt 10 a foot rod 26 mounted slidably in the bearings 27 is provided.

The upturned end 28 of the foot rod 26 is secured on the reduced portion 24 of the pin 18, by means of thecotter pin 29. The

ballof the foot of the operator depresses theclutch lever 12, so as to throw the lug .13 in engagement with the bolt 10.

The spring 20 may or may not be covered by the shield or hood 31.

-.-;.Whe'n thebolt 10 is'withdrawmthe same isflo'cked, owing-to the bolt 32 being thrown downwardly to engage the recess 33 of the 'bolt 10, against the action of the coil spring .34.- The'bolt 32 is mounted in the casing 2,

While the coil spring 34 is interposed between the shoulder 35 and the collar 36 of the bolt 32. This collar 36 is secured upon thebolt 32 by the pin 37. WVhen the bolt 32 is in a raised position its upper end portion. partiallyenters the boxing 5. A pin 'or bolt 38 is threaded into the bolt.32, and is provided with a thumb head 39. The 'pin or bolt 38 is designed to move in the slots oropenings 40 and 41 of the dash board and the plate 42, against which the thumb head 39 frictionally contacts, but not enough to retard the movement of the bolt or bind the bolt 38, but just sufiicient to' guide saidparts. vPivoted in the boxing5 upon the. bolt or pin 44 is a tumbler 45, there being a washer plate 46 between the tumbler and the cover. 7, in order to lessen frictional contact between the tumbler and the cover. This tumbler 45, is provided at each end with a laterally so extending arm. The lower arm 48 is designed to engage the upper end of the bolt 32, to hold the same downwardly depressed and in engagement with the recess 33 of the bolt 10. The upper arm 49 of the tumbler is adapted to be engaged by the arm 50 of .5, by the action of the spring 20.

the rcvoluble or rocking member 51, which 1s mounted in bearings 52 of the boxing 5. lVhen the member 51 is rocked, reference being had to Fig. 3, the arm 50 engages the arm 49 of the tumbler 45, in order to tilt the same upon its pivot 44, against the ad tion of the leaf spring 53, thus throwing the arm 48 from the path of the upper end of the bolt 32, so as to permit said bolt 32 to assume a position as shown in Fig. 4. hen the bolt 32 is in this manner released, the bolt 10 is inturn released, the same bemg returned'to the-position shown in Fig.

spring 53 is secured upon the pin or bolt 54 and engages the pin '55, so asto insure the proper tension.

It is to be remembered that any suitable 9 Yale barrel mechanism may be provided for operating the rocking member 51, for it is immaterial whatcharacter of structure, as far'as the present invention is concerned, is utilized. For illustrative purposes'this Yale barrel mechanism-may consist of a casing 56 secured inthe dash board by the screws 57 and having a barrel 58 rotatable therein, which barrel '58 is pro vided with a key opening 59 to receive any suitable form of key 60, whereby the barrel The N may be rotated. This barrel is'supplied with a tongue 61, which enters a slot 62 in the member 51. Then the barrel 58 is ro-- tatcd by virtue of the key '60, the member 51 is in turn rocked in its bearings, thus causing the arm 50 to contact with the arm 49, thereby oscillating the tumbler 45.

To release the clutch lever 12, the key 6Qv I is turned in the proper direction, in order to oscillate the tumbler, to the position shown in Fig. 4, thus releasing the bolt 32, which in turn releases the bolt 10 from engagement with the lug 13, and when 'the lug and the bolt 10 are thi'lsdisengaged, the clutch lever '12 is allowed to assume the position shown in Fig. 5.

From the foregoing in conjunction with the annexed drawings it will be ascertained that there has been devised a novel, efficient,

.simple and desirable locking mechanism for automobile clutchlevcis, and one which has been found through various experiences to be practlcal.

The invention having been set forth,
